Flow to the opposite side of the enlarged portion 56 of the piston rod 26.In this embodiment, in the piston rod 26 toward first direction D1
During shifting, the control valve 32 can be in a position P to stop (this portion of gap 60 with respect to the enlarged portion 56 of the piston rod 26
Fig. 5 can be coordinated by dividing).Therefore, under this state, a part for the buffer fluid 42 can be forced to flow to the work from the groove 40
The opposite side of the enlarged portion 56 of stopper rod 26.
As shown in Fig. 4 and Fig. 6, when the strength continues to apply to the piston rod 26 toward first direction D1, the pedestal 30
The elastic component 28 is further pushed against, the elastic component 28 is accumulated the elastic force, and a part for the buffer fluid 42 is extruded and energy
The opposite side of the enlarged portion 56 of the piston rod 26 is continued to run to from the groove 40.
As illustrated in figs. 7 and 8, when the above-mentioned strength toward first direction D1 is released, the pedestal 30 and the energy of piston rod 26
Enough respond the elastic force of the elastic component 28 and toward a second direction D2 displacements, wherein second direction D2 is with first direction D1
Opposite direction.During the pedestal 30 and the piston rod 26 are toward second direction D2 displacements, one of the buffer fluid 42
Divide and be extruded, make the part meeting of the buffer fluid 42 past away from the opening from the opposite side of the enlarged portion 56 of the piston rod 26
38 direction backflow.During this backflow, a part for the buffer fluid 42 can pass through the gap 60；Or, the buffering
A part for fluid 42 can pass through the groove 40.Wherein, by the pedestal 30 respond the elastic component 28 the elastic force toward this second
Direction D2 displacements, enable the control valve 32 close to the pedestal 30.In simple terms, the control valve 32 away from above-mentioned position P not
Stop the gap 60；Or, flowed back by a part for the buffer fluid 42, make the control valve 32 can be from above-mentioned position P by this
A part for buffer fluid 42 drives and energy is close to the pedestal 30 towards the displacement of pedestal 30, and in other words, the control valve 32 is also
Can be accordingly away from above-mentioned position P.
It follows that the single structure that the piston rod 26 for the buffer unit 22 that embodiments of the invention are provided is one of the forming
The width of the enlarged portion 56 of part, wherein piston rod 26 is more than the bar portion 52；In addition, the cylinder body 22 is provided with the groove 40, for
Buffer fluid 42 passes through.
Explanation more than, it is known that enhancement effect of the invention is to be with advantage：To realize piston rod combination piston
For solid memder, and it can reach the pooling feature of reinforced structure.
Although the present invention is described with reference to current specific embodiment, those of ordinary skill in the art
It should be appreciated that the embodiment of the above is intended merely to the explanation present invention, it can also make in the case of without departing from spirit of the invention
Go out it is various equivalent change and modifications, therefore, as long as in the spirit of the present invention to the change of above-described embodiment, become
Type will all fall in the range of the application claims.
